The Lamborghini Sesto Elemento (literally "Sixth Element" in Italian) is a two-seater, V10 high-performance concept car produced by Italian automaker Lamborghini, which debuted at the 2010 Paris Motor Show. The Sesto Elemento is equipped with a 6-speedpaddle-shift, semi-automatic transmission and all-wheel-drive system, mated to a 5.2-litre V10 engine borrowed from the Lamborghini Gallardo, generating 570 horsepower and 540 Nm (398) ft-lb of torque. The chassis, body, driveshaft and suspension components are made of carbon fiber, reducing the overall weight to a mere 999 kilograms (2,200 lb), making it the lightest car Lamborghini has ever produced. Air is released through 10 distinctive hexagonal holes in the engine cover, while two intakes funnel cool air into the mid-mounted engine compartment. The Sesto Elemento's high amount of horsepower combined with low overall weight translate to a power-to-weight ratio of 0.57 hp/kg (0.26hp/lb). Lamborghini claims a 0–100 km/h (0-62 mph) acceleration time of just 2.5 seconds, and a top speed of 350 km/h (217 mph). Lamborghini sources said "...It will never be road legal". AutoWeek magazine said a "...A stratospheric price tag, perhaps about $1.7 million..." The Sesto Elemento's name stems from the car's extensive use of carbon fiber, carbon being the sixth element in the periodic table of elements. Lamborghini plans to make 20 Sesto Elementos for track use only.
